Machine learning can be applied to time series datasets.
  These are problems where a numeric or categorical value must be predicted, but the rows of data are ordered by time.
  A problem when getting started in time series forecasting with machine learning is finding good quality standard datasets on which to practice.
  In this post, you will discover 8 standard time series datasets that you can use to get started and practice time series forecasting with machine learning.
  After reading this post, you will know:
  
       
  • 4 univariate time series datasets.   
  • 3 multivariate time series datasets.   
  • Websites that you can use to search and download more datasets.  
  Let’s get started.
  Univariate Time Series Datasets

  Time series datasets that only have one variable are called univariate datasets.
  These datasets are a great place to get started because:
  
       
  • They are so simple and easy to understand.   
  • You can plot them easily in excel or your favorite plotting tool.   
  • You can easily plot the predictions compared to the expected results.   
  • You can quickly try and evaluate a suite of traditional and newer methods.  
   The website Data Market provides access to a large number of time series datasets. Specifically, the Time Series Data Library created by Rob Hyndman , Professor of Statistics at Monash University, Australia
  Below are 4 univariate time series datasets that you can download for free from Data Market from a range of fields such as Sales, Meteorology, Physics and Demography.
  Shampoo Sales Dataset

  This dataset describes the monthly number of sales of shampoo over a 3 year period.
  The units are a sales count and there are 36 observations. The original dataset is credited to Makridakis, Wheelwright and Hyndman (1998).
  Below is a sample of the first 5 rows of data including the header row.
  [code]"Month","Sales of shampoo over a three year period"
"1-01",266.0
"1-02",145.9
"1-03",183.1
"1-04",119.3
"1-05",180.3
[/code]  Below is a plot of the entire dataset taken from Data Market.

  Minimum Daily Temperatures Dataset

  This dataset describes the minimum daily temperatures over 10 years (1981-1990) in the city Melbourne, Australia.
  The units are in degrees celsius and there are 3650 observations. The source of the data is credited as the Australian Bureau of Meteorology.
  Below is a sample of the first 5 rows of data including the header row.
  [code]"Date","Daily minimum temperatures in Melbourne, Australia, 1981-1990"
"1981-01-01",20.7
"1981-01-02",17.9
"1981-01-03",18.8
"1981-01-04",14.6
"1981-01-05",15.8
[/code]  Below is a plot of the entire dataset taken from Data Market.

   Minimum Daily Temperatures
    The dataset shows a strong seasonality component and has a nice fine grained detail to work with.

  Monthly Sunspot Dataset

  This dataset describes a monthly count of the number of observed sunspots for just over 230 years (1749-1983).
  The units are a count and there are 2,820 observations. The source of the dataset is credited to Andrews & Herzberg (1985).
  Below is a sample of the first 5 rows of data including the header row.
  [code]"Month","Zuerich monthly sunspot numbers 1749-1983"
"1749-01",58.0
"1749-02",62.6
"1749-03",70.0
"1749-04",55.7
"1749-05",85.0
[/code]  Below is a plot of the entire dataset taken from Data Market.
